Installation Example
OM-120 is an expansion module for floor access control. Combined with Suprema device and BioStar 2, a single module can control 12
floors. When the OM-120 is connected as daisy chain via RS-485, you can control up to 192 floors per elevator.

Power
•Do not share the power with the access controller.
RS-485
•RS-485 should be AWG24, twisted pair, and maximum length is 1.2 km.
•Connect a termination resistor (120Ω) to both ends of a RS-485 daisy chain connection. It should be installed at both ends of the daisy
chain. If it is installed in the middle of the chain, the performance in communicating will deteriorate because it reduces the signal level.
•Up to 31 modules can be connected to the master device.
